Water cooling your PC isn't just for geeks any more, not with the Water Cowboy DC-WCP450, which brings on the coolness by teaming up the power supply with the radiator, pump and water tank. It's reportedly the first water cooling system built into a power supply. The 12cm fan keeps the power supply from getting too hot and at the same time cools off the water, which is moved down to a processor cooling unit through a couple of tubes.

So if you're looking to do some serious overclockage, this kit has everything you need to cool off that PC, all the way down to a bottle of coolant. Best of all, the Water Cowboy keeps all the paraphernalia inside the case, where no one will be the wiser.
